- W2020147822 abstract "The decay of the photoluminescence for VPE-GaAs1-x,Px:N. Te for x = 0.96, 0.89, 0.88, 0.80, and 0.70 at room temperature is investigated. Experimentally it is verified that even for VPE-GaAs1-xPx: N, Te (x ≥ 0.70) the photoluminescence decay behaviour at room temperature is determined by nonradiative recombination processes. Taking into account the pecularities of the mixed crystal system relative to the case of VPE-Gap: N, Te, the photoluminescence decay measurements can be interpreted in the same manner as for VPE-Gap, and analogeous connections between Pen the excitation intensity depending photoluminescence decay time and the minority carrier lifetime are valid. To clarify the influence of the increasing radiative recombination probability (with increasing As content) the relative efficiency for different alloy compositions is obtained by time-integrated measurements of the photoluminescence intensity after pulsed excitation. The influence of the surface recombination on the pliotoluminescence decay is demonstrated using different wavelengths of the exciting light. The optimum wavelengths of the exciting light for minority carrier lifetime measurements for the z-values used are given. Investigating the dependence of the maximum photoluminescence intensity on the excitation intensity the equilibrium concentration of free carriers can be obtained purely from optical measurements. For the whole z-range of interest (x = 0.70) the time behaviour of the photoluminescence at room temperature is determined by the simultaneous influence of point defects and dislocations. With rising As content the dislocation density increases, probably because of the increasing misfit between the GaP substrate and the GaAs1–xPx layer, and the recombination via dislocations becomes more important. For typical injection levels for LEDs for the yellow-emitting matrial (x = 0.88) the recombination via point defects, and for the red-emitting material (x = 0.70) that via dislocations dominate.Es wird das Photolumineszenzabklingen fur VPE-GaAs1-xPx:N, Te fur 2 = 0,96; 0,89; 0,88; 0,80 und 0,70 bei Raumtemperatur untersucht. Es wird experimentell nachgewiesen, das auch fur VPE-GaAs1-xPx: N, Te (x ≥ 0,70) das Photolumineszenzabklingverhalten bei Raumtemperatur durch nichtstrahlende Rekombinationsprozesse bestimmt wird. Unter Berucksichtigung der Besonderheiten des Mischkristallsystems gegenuber VPE-GaP konnen die Photolumineszenzabklingmessungen in derselben Art und Weise wie fur VPE-GaP interpretiert werden, und zivisclicn der anregnngsintensitatsabhangigen Photolumineszenzabklingzeit und der Minoritatstragerlebensdauer bestehen dieselben Zusammenhange. Um den Einflus der (mit wachsendem As-Gehalt) zunehmenden strahlenden Rekombinationswahrscheinlichkeit zu klaren, wird die relative Effizienz fur verschiedcne Zusammensetzungen mittels zeitintegrierter Messungen der Photolumineszenzintensitat nach Impulsanregung ermittelt. Der Einflus der Oberflachenrekombination auf das Abklingen der Photolumineszenz wird durch Anwendung verschiedener Wellenlangen des anregenden Lichtes demonstriert. Die fur die Messung der Minoritatstragerlebensdauern optimalen Wellenlangen des anregenden Lichtes fur die hier benutzten x-Werte sind angegeben. Durch die Untersuchung der Abhangigkeit der maximalen Photolumineszenzintensitat in Abhangigkeit von der Anregungsintensitat kann die Gleichgewichtskonzentration der freien Ladungstrager ausschlieslich durch optische Messungen bestimmt werden. Bei Raumtemperatur wird fur den gesamten hier interessanten x-Bereich das Zeitverhalten der Photolumineszenz durch die gleichzeitige Wirkung von Punktdefekten und Versetzungen bestimmt. Mit zunehmendem As-Gehalt vergrosert sich die Versetzungsdichte, wahrscheinlich bedingt durch die zunehmende Fehlanpassung zwischen Gap-Substrat und GaAs1-xPx-Schicht, und die Rekombination uber Versetzungen wird wichtiger. Fur typische Injektionsniveaus der LEDs ist fur gelbleuchtendes Material (x = 0,88) die Rekombination uber Punktdefekte, fur rotleuchtendes Material (x = 0,70) die uber Versetzungen dominierend." @default.
